Floor Cleaning Head Support Structure for Higher Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines lack optimal design for efficient dirt collection and easy operation, particularly in terms of supporting the weight of the cleaning head and maintaining a stable position during cleaning, which affects cleaning efficacy and usability.
Innovation Solution
The floor cleaning machine incorporates a continuous recess in the dirty fluid tank device that allows it to be supported by a support element, enabling the tank to be held floating on the base and providing a large holding volume, while the cleaning head is supported by both the cleaning roller unit and the support element, allowing for improved contact pressure and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the cleaning head is supported only by the cleaning roller unit, then the structure is simple, but the contact pressure is insufficient and cleaning efficacy is reduced
Solution Approach 1:
The support function is segmented into two independent elements: the cleaning roller unit for primary support and the support element for additional support. This segmentation allows each element to perform its specific function optimally while together they provide sufficient contact pressure without excessive complexity.
Solution Approach 2:
The support element acts as an intermediary component that bridges the gap between the cleaning head and the floor. It provides additional contact points and distributes the weight, thereby increasing contact pressure without requiring a complete redesign of the support structure.
2Quantity of substance
If the dirt fluid tank device is fixed solidly to the base, then the tank is stable, but the holding volume is reduced and ease of operation is worsened
Solution Approach 1:
The support element is nested through the dirt fluid tank device, passing through a through-opening in the base. This nested arrangement allows the tank to be held in a floating manner without solid fixation, maximizing the holding volume while maintaining stability through the support element's engagement with both the cleaning head and the floor.
Solution Approach 2:
The tank device transitions from a static fixed connection to a dynamic floating support arrangement. The support element allows the tank to adjust its position dynamically while maintaining stability, improving both holding volume and ease of operation for removal and insertion.
3Productivity
If the support element is added to increase contact pressure, then cleaning efficacy is improved, but the device complexity increases
Solution Approach 1:
The support element serves multiple functions simultaneously: it provides additional contact pressure for cleaning efficacy, supports the cleaning head weight, and acts as a structural connector between the cleaning head and the floor. This multi-functionality increases productivity without proportionally increasing device complexity.
Solution Approach 2:
The support element is merged with the existing cleaning head structure and base assembly. Rather than being a separate complex subsystem, it is integrated into the overall structure, combining the support function with the existing components to minimize additional complexity while maximizing cleaning efficacy.
